CUSPIDOR.

Application filed March 21, 1908.

To all whomy it may concern:

Be it known that I, VILLIAM C. BRIDGES, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Cuspidors, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a cuspidor, particularly adapted for use in the fioors of street cars and railway coaches, and the object of my invention is to construct a cuspidor which lies flush with the surface of the floor, and which can be readily opened by foot pressure.

To the above purposes, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of a cuspidor of my improved construction inposition'for use;

'Fig. 2 is a vertical section taken on the line 2 2 of Fig. l; and Fig. 3 is a rear elevation of the cuspidor.

Referring by numerals to the accompanying drawings: l designates the bowl which forms the body of the cuspidor, and formed integral with the top thereof is a ring 2, which is let into the floor of the car so that its top surface is flush with the surface of said floor, and said ring being fixed in position by means of screws 3 or similar fastening devices.

Hinged by means of a pin 4 to one side of the ring is a cover plate 5, the top surface of which lies flush with the top surface of the ring 2 when said cover is closed, and formed between the hinge ears on said cover is a recess 6, and formed in the upper portion of the bowl immediately adjacent this recess 6 is a corresponding recess 7. Fitted into these recesses 6 and 7 is a leaf spring 8, the tendency of which is to swing the cover plate 5 upward into a vertical position.

9 designates a plate which closes the lower end of the bowl l when the cover plate is swung open, which plate 9 swings on a vertically disposed pivot pin 10, seated in the under side of the bowl, and formed integral with the plate and projecting outward from Specification o1" Letters latent.

the point where the same arm 1]..

l2 designates a rod which is pivotally connected to the end of the arm 1l, and the upper end of said rod is pivotally connected to a lug 13 formed integral with one of the hinge ears of the cover plate 5.

Formed integral with the ring 2, directly opposite the point where the cover plate is hinged, is a vertically disposed housing le, in which is arranged for rotation a disk l5; and formed integral with said disk and operating through a bearing in the bottom of the housing 14 is a pin 16.

17 designates an expansive coil spring which is arranged on the pin I6 between th under side of the disk 15 and the bottom of the housing 14.

Formed integral with the under side of the disk l5 is a U-shaped loop I8, having a beveled top surface, and bearing on said beveled top surface is the corresponding beveled face of a block 19, carried by a horizontally disposed latch pin 20, operating through the upper portion of the wall of the bowl l, and there being an expansive coil spring 2l located onsaid latch pin behindthe block 19.

The end of this latch pin opposite the block 19 projects into the bowl l and normally engages in a notch 22 formed in a lug 23 which is integral with and projects downward from the cover plate 5.

The end of the in 21 within the bowl l is beveled, and the lbwer end of the lug 23 is rounded, in order that when the cover plate 5 is moved downward to close the top of the bowl, the lug will bear upon the beveled end of the pin and force the same rearward in order that the point of the pinl may engage in the notch 22 to hold the cover plate closed.

To open a cuspidor of my improved construction, the disk I5 is forced downward against the pressure exerted by the coil spring 17, and this movement carries the loop 1S downward, and following this action the coil spring 21 exerting a pressure behind the block I9 causes said. block to move laterally a short distance, thus withdrawing the point of the latch pin 20 from the notch 22. As soon as this action takes place, the power stored in the leaf spring 8 immediately swings the cover plate into an approximate vertical plane, thus opening the top of the bowl, and

is pivoted is an simultaneous with this action the lug 13 onl the rear side of the cover plate moves downward, thus moving the rod 12 downward and in turn swinging the arm 11 forward and il bringing the plate 9 into position to close the engages in the notch 22, and as this movement takes place the plate 9 is swung laterally away from the lower end ofthe bowl, andk the matter deposited on said plate 9 is scraped ofl" by the edge of said bowl.

My improved cuspidor is simple in construction and operation, can be readily opened and closed, and when set inthe Vfloor ci a car for use lies flush with the surface of the floor, and therefore offers no obstruction to the occupants of the car.

I claim 1 1. A cuspidor, comprising a bowl, a cover plate hinged thereto, a spring connected to the cover plate in such a manner as to swing said plate open when sai-d plate is unlocked, a plate pivotally connected to the lower end of the bowl and adapted to swing in a horizontal plane, a link connecting a portion of the cover plate and the rear endl of the plate at the lower end of the bowl, a horizontally disposed spring actuated latch pin normally engaging a portion of' the cover plate when the same is closed, a spring held disk arranged in the top of the bowl, and a loop carried by said disk, which loop normally engages one end of the latch pin which holds the cover plate closed.

2. A cuspidor comprising a bowl and a cover plate hinged thereto to swing in a vertical plane, a spring connected to said cover plate and adapted toswing the same open when said. cover plate is unlocked, a spring actuated latch arranged in the bowl and adapted to engage the edge ofthe cover plate opposite the point where the same is hinged, a plate pivotally connectedy to the lower end of the bowl, and adapted to swing in a horizontal plane,. and a link connecting a portion of the cover plate and the rear end of the plate at the lower end of the bowl for swinging the plate at the lower end of the bowl into an open position when the cover plate is closed..

In testimony whereof, I have signed my name to this specication, in presence of two subscribing witnesses.
